Project Summary Child obesity disproportionately impacts young Latino children and has important implications for later adulthood weight and health problems. In-person parent-focused obesity prevention and control interventions are effective in establishing healthy weight behaviors and weight outcomes for young children, including Latino children. Widespread dissemination in healthcare and community settings pose several challenges including family participation barriers of time, cost, transportation, and English proficiency. The study goal is to pilot a stand-alone mobile phone intervention with Latino mothers, fathers, and grandparents, geared at building caregiver strategies to support evidence-based and age appropriate dietary, media-viewing, and physical activity practices among 2- to 5-year old children in order to resolve key challenges of traditional in- person pediatric obesity interventions (e.g. transportation, time), and also leverage important determinants of Latino health (e.g. familism, language). A prospective control group pilot study will be completed to assess acceptability, feasibility, and preliminary effect sizes on children's weight-related behaviors and BMI z-scores at 6 months post-intervention, in preparation for a larger randomized trial to evaluate the intervention's efficacy. The intervention will deliver 4 interactive texts every week for one month to Latino caregivers of 2 to 5-year old children and 2-months of mobile phone “booster” doses that incorporate behavioral change techniques using a group strategy, a cornerstone of many effective in-person parent-focused pediatric obesity interventions. The study will first use qualitative methods to maximize the acceptability and usability of the existing mobile phone group learning strategies with a small group of Latino mothers, fathers, and grandparents. A 4-week mobile phone pilot intervention will then be completed with 66 caregiver-child dyads recruited from two WIC sites in East Los Angeles. Eligible caregiver-child dyads will be randomly assigned into the mobile phone intervention group or the comparison group, in which caregivers receive usual WIC services. Acceptability and feasibility outcomes will include: (1) the number of families needed to be screened per month; (2) attrition rates of a mobile phone intervention with Latino populations; (3) dose and exposure of texts; (4) frequency of sharing/replying to texts by caregiver-type; (5) number of completed baseline and follow-up data; and (6) family-centeredness of the intervention. Pre- and post- intervention data will be collected at baseline, 1-month, and 6-months after the intervention begins in order to estimate preliminary effect sizes and standard deviations associated with child dietary, physical activity, and media viewing practices and BMI scores. Mediators of the intervention will include measures of caregiver self-efficacy, caregiver feeding practices, and group support. The pilot study will provide the acceptability, feasibility, and preliminary data on child weigh-related behaviors and BMI to develop an R01 proposal to test the intervention's effectiveness via a randomized controlled trial.

项目摘要 儿童肥胖不成比例地影响年轻的拉丁裔儿童，并对以后的生活产生重要影响。 成年体重和健康问题。以家长为中心的肥胖预防和控制干预措施 有效地建立健康的体重行为和体重结果的幼儿，包括拉丁美洲人 孩子在医疗保健和社区环境中的广泛传播带来了几个挑战，包括 家庭参与的时间、成本、交通和英语水平的障碍。本研究的目标是试点一个 独立的移动的电话干预与拉丁美洲的母亲，父亲和祖父母，面向 建立护理人员策略，以支持基于证据和年龄适当的饮食，媒体观看， 2至5岁儿童的体育活动，以解决传统教育的主要挑战， 儿童肥胖干预措施（如交通，时间），并利用重要的决定因素， 拉丁美洲人的健康（如家庭主义、语言）。将完成一项前瞻性对照组试点研究，以评估 儿童体重相关行为和BMI z分数的可接受性、可行性和初步效应量 干预后6个月，为更大规模的随机试验做准备，以评估干预的有效性。 该干预措施将在一个月内每周向2至5岁的拉丁美洲护理人员提供4个互动文本 儿童和2个月的移动的手机“助推器”剂量，其中包括使用 小组策略是许多有效的以家长为中心的儿童肥胖干预措施的基石。的 研究将首先使用定性方法，以最大限度地提高现有移动的电话的可接受性和可用性 小组学习策略与一小群拉丁美洲的母亲，父亲和祖父母。为期4周的移动的 电话试点干预将完成与66个两个儿童二对招募从两个WIC网站， 东洛杉矶。符合条件的父母-子女二人组将被随机分配到移动的电话干预组 组或对照组，其中照顾者接受常规WIC服务。可接受性和可行性 结果将包括：（1）每月需要筛查的家庭数量;（2） 拉丁裔人群的移动的电话干预;（3）文本的剂量和暴露;（4） （5）完成的基线和后续数据的数量;（6） 以家庭为中心的干预。将在基线、1个月、 干预开始后6个月，以估计初步效应量和标准差 与儿童饮食、体育活动、媒体观看习惯和BMI评分相关。调解员 干预措施将包括照顾者自我效能、照顾者喂养做法和团体支持的措施。 这项先导性研究将提供儿童体重相关行为的可接受性、可行性和初步数据 和BMI制定R 01建议，通过随机对照试验测试干预的有效性。
